It is based on the Tb(III)-sensitized luminescence that is plasmonically enhanced by silver nanoparticles (Ag NPs). The emission of the Tb(III) complexes has maximum at 545nm after excitation at 284nm and is strongly enhanced in the presence of the colloidal Ag NPs. Under optimum experimental conditions, luminescence intensity increases linearly with the concentration in the range from 4.16 × 10-17-3.59 × 10-15M of LEV, and from 4.98 × 10-17-2.49 × 10-15M for MOXI with correlation coefficients of 0.9996 and 0.9996, respectively. The limits of detection are 7.19 × 10-18M and 8.47 × 10-18M, respectively, and the relative standard deviations are 1.3 and 1.5% for 5 replicate measurements at 6.08 × 10-14M of LEV and 5.48 × 10-14M of MOXI. The method was successfully applied to the determination of LEV and MOXI in pharmaceutical samples, in urine and in serum. Figure A new luminescent terbium(III)-fluoroquinolones (FQs) framework with silver nanoparticles exhibits a highly sensitive fluorescent response towards Tb3+ ion. The luminescence intensity of the framework was enhanced significantly by Ag NPs with the concentration of FQs which showed a good linear relationship and detection limit.
